Which of the following is Isaac Newton NOT known for

• Developing scientific laws

• Developing the telescope

• Developing a new math

• Discovering what light is

A scientific law is...

• an explanation of a scientific theory

• a statement that explains a phenomenon

• a fact that cannot be proven wrong

• a statement or mathematical description of a natural phenomenon

How many laws did Newton publish in Principa?

• 2

• 3

• 4

• 5

The three other laws Newton published are called

• Newton's Laws of Motion

• Newton's Laws of Forces

• Newton's Laws of Physics

• Newton's Laws of Gravity

Net force is

• The largest force acting on an object

• The smallest force acting on an object

• The sum of all forces acting on an object

• The force an object exerts on another object

Forces have BOTH

• direction

• volume

• mass

• magnitude (strength/size)

When all forces on an object are in the SAME direction, you find the net force through

• adding

• subtracting

• multiplying

• dividing

When forces are acting on an object in OPPOSITE directions, you find the net force by

• adding

• subtracting

• multiplying

• dividing

When you have to subtract to find the net force, the direction of the net force will be

• in the direction of the weaker force

• in the direction between both forces (diagonal)

• in the direction of the stronger force

• in the direction of the weaker force

True or False: The net force acting on an object can be 0N.

• True

• False
